Why Professionals Choose the Hytera MD785 VHF
The MD785 VHF is a vehicle-mounted mobile radio — 60×174×200 mm, 1.7 kg — built for dashboard or console installation in fleet vehicles, dispatch units, and site command posts. At 50W high power on 136–174 MHz, it delivers the output range needed for transportation fleets, port ground operations, construction site vehicles, and public works teams covering large outdoor territories where handheld radios fall short on range.
The radio draws power from the vehicle's 13.6V DC supply and handles the full DMR Tier II/III feature set: TDMA dual-slot operation doubles channel capacity on the same spectrum allocation, XPT pseudo-trunking dynamically assigns slots without a dedicated control channel, and DMR Tier III trunking is available via software licence. Mixed dual-mode operation — digital and analog on a per-channel basis — keeps the MD785 VHF compatible with existing analog VHF infrastructure during fleet migration. Seven programmable keys and the large-format keypad microphone support hands-free and in-cab operation.
IP54 protects against dust ingress and water splashing from any direction. MIL-STD-810 C/D/E/F covers temperature extremes from –30°C to +60°C, shock, vibration, humidity, salt fog, and sand — the certification set appropriate for vehicle-mounted equipment in outdoor industrial environments. The 2.0-inch TFT color display (220×176 px, 262,000 colors) provides clear channel and status readout from the driver's seat.
The MD785G VHF adds integrated GPS with cold-start TTFF under 1 minute, warm-start under 10 seconds, and horizontal accuracy under 10 meters. GPS position data and location-based text messages are viewable on the display and reportable to Hytera dispatch software. FCC Part 90 licensed.

FCC Licensing and Compliance Support
The Hytera MD785 and MD785G VHF operate on licensed Land Mobile Radio frequencies under FCC Part 90. A valid FCC Business Radio License is required for each VHF frequency used in commercial vehicle operations in the United States.
VHF frequencies in the 136–174 MHz range are commonly allocated for transportation, fleet, construction, and outdoor field operations. Frequency coordination is required as part of the licensing process to avoid interference with existing licensees in your area.
As an authorized Hytera dealer, AXDIGITAL supports customers with licensing guidance, frequency coordination, and fleet programming. Contact our team to confirm frequency availability and bulk pricing for your vehicle fleet.
FAQ
What is the difference between the MD785 VHF and MD785G VHF?
Both models share the same VHF platform, 136–174 MHz range, 50W output, IP54 rating, and accessory ecosystem. The MD785G VHF adds an integrated GPS module - TTFF under 1 minute from cold start, accuracy under 10 meters — and supports GPS position reporting and location-based text messaging via Hytera dispatch software. If real-time vehicle tracking or fleet visibility is required, specify the MD785G at time of order.
How does the MD785 VHF differ from the PD785 VHF portable radio?
The MD785 VHF is a vehicle-mounted mobile radio - 50W output, 13.6V DC vehicle power, 1.7 kg, 5W built-in speaker — installed on a dashboard or console. The PD785 VHF is a portable handheld radio — 5W output, 355g, Li-Ion battery. The MD785 VHF is chosen when coverage range, in-vehicle installation, and high output power matter. The PD785 VHF is chosen when personnel need to carry the radio on foot.
Can the MD785 VHF be used as a desktop base station?
Yes. With the optional PS22002 300W mobile power supply, the MD785 VHF operates as a desktop or fixed base station connected to mains power. This configuration is used in site offices, dispatch centers, and command posts where a vehicle-grade radio needs to run from AC power rather than a vehicle's DC system. A suitable external VHF antenna and appropriate cabling are also required.
